The voltage should actually be at 14 when you're in ready mode. It should drop when you're actually driving, between 12 and 13.

Thanks for this video! Gives me hope for my little Prius yet.

TONY,T, I'VE HAD THIS HAPPEN TO ME TWICE ON MY 2008 PRIUS THAT MY WIFE DRIVES. EACH TIME SHE GOT HOME WITH IT, ALL THE DASH LIGHTS WERE ON INCLUDING THE TRIANGLE W/ EXCLAMATION. ALL I COULD THINK OF REAL QUICK WAS, THESE CARS EVEN CONVENTIONAL ARE COMPUTERS ON WHEELS (REBOOT). SO I DISCONNECTED THE BATTERY POST AT THE FUSE BOX UNDER THE HOOD, RECONNECTED AFTER ONE MINUTE AND ALL WENT BACK TO NORMAL AGAIN.I'M NOT SAYING I KNOW WHAT I'M DOING BUT IT WORKED FOR ABOUT TWO MONTHS BEFORE DOING IT THE SECOND TIME. I HAD THE CODE CHECKED AFTER THE SECOND REBOOT AND SHOWED (1256) WHICH I WAS TOLD MEANT THE BRAKE ACTUATOR, A $2000.00 JOB. I'LL PUT THAT OFF UNTIL THE REBOOTS QUIT WORKING . HOPE THIS HELPS SOMEBODY.

You saved my life today thank you❤️❤️

Hey everybody. After an unusual cold spell the 12V starter battery was shot again. I bought it in 2019 so it shouldn`t have quit. Often times these batteries have a three year warranty. So double check the date on the battery and/or the receipt if you still have it. They swapped mine for 0 Dollars!

I really cant give you advice on that. I am always too frugal to buy overpriced parts at the original dealer unless absolutely necessary. We bought ours aftermarket. So far so good... :-)

Sorry if stupid question but when you say replace the 12v battery is this one one under the bonnet or right side in the boot?

Not a stupid question. Yes, the Prius -just like any other car- has a 12V starter battery. In my 2008 Prius model it is located in the back on the passenger side in a little compartment. You have to empty out the back, lift the big hatch thing and loosen a few screws to replace it. You can see it as you go what needs to be unscrewed. Good luck.

This exact thing happened to me today. My Prius 2006 hadn't been started since more than a month. It was dead . So today I jump started it with the help of a friend's car. And as soon as I began driving, within a few meters, the Check Engine light, the Master Warning red triangle and the Hybrid System Warning indicator appeared. I am just thinking of taking your advice and getting the 12v battery replaced. Any thing else you would suggest? I would appreciate your input if possible, and Thanks for the video.

One thing I did was after this all happened to me on one occasion the new starter battery went low again. I disconnected the battery from the car and charged it with a trickle charger, it took half the day but then was fine ever since. Good luck to you!! Let me know how it went...

Look first at the Inverter Coolant level. I had the same problem and after a while I noticed there was no coolant in the Inverter coolant reservoir. I filled it with filtered water and straight away the errors went away and the Hybrid System was working again. Then I noticed liquid coming out of the radiator....a rock had made a small hole in the inverter coolant radiator (the little one on top.). I found another inverter coolant radiator and replaced it. Put it all back together and no more problems.

Sorry I didn’t see your comment. Maybe something else is wrong too. Have it checked by a Toyota dealer. Reading the codes does cost though. I know that for our Prius model there was a recall for the hybrid cooling system pump. Only a Toyota dealer would know if that applies to your model.

I am not mad. :-) Gave me the chance to figure it out myself.

Also keep in mind every time you disconnect the battery all settings are lost radio etc. I charged the battery once with a trickle charger and it worked fine. I did disconnect it from the car system though. I do not believe the 200mpg thing... that seems to be too good to be true. Our Prius is a 2008 and we can not plug it in.

I can't thank you enough. My 05 Prius was low on oil, as I kept driving to get home, the red "triangle" came on. After servicing the oil and restting the service req. light. The red warning light remained. It's just an old car that I use to keep milage off my newer vehicles, and I got it for a very low price. I disconnected the rear battery for 20 seconds after watching your video. I then reconnected it and all warning lights are now off. I hope to get a few more years out of this vehicle.

I am not sure. I would do the battery test. How old is the battery? It also depends on the codes they are reading. Ask them if they have a battery to put in to test it. It may take a bit of driving though for everything to reset.

There is a terminal to jump start the Prius. It is under the hood in one of the fuse boxes. The positive goes on that terminal, the negative somewhere on the chassis. I am not sure what could have happened. Maybe you blew a fuse, maybe you damaged more than that be reversing polarity (did I read the correctly?). I would search the internet and/or get an OBD 2 reader and read the error codes. Sorry that happened! Hope it can get fixed. Get your momma some flowers. :-)
